The first cloud for classified information.
The Cloud for the Public Sector That Complies with Classified Information Requirements
Defense, internal security, and government agencies work with information subject to strict security requirements. SINA Cloud makes modern cloud technology available for this sector—without compromising on security and control. Based on the SINA ecosystem, a cloud platform is being developed that processes classified information up to the “SECRET” level in compliance with legal requirements and is operated with full sovereignty.
SECURITY-BY-DESIGN
Uncompromisingly secure, flexibly scalable
SINA Cloud combines a security layer with components approved for use by the BSI and a cloud orchestration layer. This architecture structurally separates security functions from orchestration operations, allowing the feature set to be expanded and updated without compromising VSA compliance—a clear advantage over cloud platforms that have been retroactively hardened.

Components with German Federal Office for Information Security (BSI) operational approval form the foundation of security and can be secured independently of the rest of the cloud stack.
Open-source technologies such as Kubernetes and OpenStack enable modern, standardized cloud operations.
The range of functions can be continuously expanded and updated without jeopardizing the operating license.
PERFORMANCE-BY-DEFAULT
Focus on Operations
In addition to authorization for classified information, SINA Cloud focuses on automated, easy-to-manage cloud operations. Modern cloud technology can be deployed confidently and securely on-premises—with a highly standardized operational concept.
YAOOK Life-Cycle Management
YAOOK optimizes and automates the entire life-cycle management of the cloud stack—from rollout to maintenance.
Resilience & Availability
Numerous resilience mechanisms ensure high availability and efficiency during ongoing operations.

MULTITENANCY
Multitenancy and Resource Efficiency
The core concept of the cloud is the virtualized and shared use of resources such as servers, networks, and storage. SINA Cloud enables the simple and scalable provisioning of virtual resources for operating cloud services - ideal for operators who want to support multiple clients on a single infrastructure.
VSA COMPLIANCE
Working with Classified Information in Compliance with the Law
SINA Cloud meets the requirements of Section 51 of the Classified Information Directive (VSA) and enables the legally compliant use of external cloud infrastructures. When planning, testing, and implementing a VSA-compliant cloud, secunet’s cloud experts provide support based on their experience—including their involvement in the Federal Measure R-VSK for the Foreign Office’s overseas IT operations.

FLEXIBILITY
Flexibility Thanks to Hardware Independence
SINA Cloud runs on any standard hardware and does not require any special platforms or proprietary hardware. This reduces dependence on individual manufacturers and provides planning certainty throughout the entire procurement and operating cycle.
- Runs on standard server hardware without vendor lock-in
- Existing data center infrastructure can continue to be used directly
- Independent procurement of hardware and software—no bundled product package

TECHNOLOGICAL FOUNDATION
Built on proven open-source standards
SINA Cloud relies on a broad foundation of established open-source technologies. This ensures transparency and auditability while reducing dependence on individual vendors - without having to forego industry-proven standards.
Orchestration
Kubernetes and OpenStack form the core of the cloud orchestration layer - industry-proven and in use worldwide.
Life Cycle & Automation
YAOOK automates the lifecycle management of the entire cloud stack - from rollout and updates to operational control.
Network Security
strongSwan, a proven open-source IPsec solution, secures network connections - combined with other tested security components.
SINA ECOSYSTEM
Welcome to the VS Ecosystem
SINA Cloud is not a standalone solution. It expands the proven SINA ecosystem with a modern cloud platform—and thus seamlessly integrates with approved clients, crypto gateways, and network components that government agencies and organizations are already using.
Secure Clients
SINA Workstation, SINA Mobile, and SINA Tablet as approved end devices for accessing cloud resources up to the SECRET classification.
Cryptographic Gateways
SINA L3 Box and SINA VPN secure the network connection—for protected connections between locations and the cloud infrastructure.
Management & Operations
SINA Management and SINA Remote Management enable centralized administration of distributed SINA infrastructures, including cloud components.
Fully managed infrastructure in certified, high-security data centers in Germany.
BSI operational authorization and VSA compliance remain fully intact—even in the “as-a-service” model.
secunet handles life-cycle management, updates, and operations—allowing organizations to focus on their core applications.
